IMPROVEMENTIN,wATEteeRf-rss.

The ASchedule referredto in these mettersi-Patent andx'naking part of the samel To alljvhoin it mayconcemr.-

Be it yknown that- I, JOSEPH RYAN, 'of St. Louis,

inthc county of St; Louis and State vvof `Missouri, Vhave made certain new and usefnijlmprovements in Circnlators and Steam-Generators; and I do hereby declare that the following is va -full and .true descrip/- tion thereof, reference being` had tothe accompanying drawing andto the letters ofreiereuce'markgd 1tljeye0n,. This invention relates- A l, Firstly, to an improved arrangement of supply-pipes fcrfe'edingthe water to the grate-bars, and the manner o'fiegulating the supplyand flow oi' the water to said grate-bars;

Secondly, to the peculiar arrangement and vcon-` struction of the grate-bars proper;

. Thirdly, to the. arrangement 'of the parts forming .an improved circulator, by meausof which a continu? ons circulation of the Water from the boilers and through the gratefbals is achieved; and L Lastly, said invention relates to certain detail con-J struction of parts, hereinafter to loe more fully described. I

To enablethose. herein skilled to makeand" my said invention, I will now more fully-'describe the same,rreferring to the accompanying s `Iignre-l as aside elevation;` to

Figure 2 as a top planin general; to

` Figureas a front elevation, representing my im-` Yp rovements adapted to two or moreboilers and to Figure 4 as an enlarged detail part section and top plan of the grate-bars.

The grate-bars A are supported-inv the usual-'conf strueted furnace-chamber'. Said grate-bars consistof hollow pipes arranged in duplicate sections, A1 and A2, joined at `t-heirrear endsby properreturu bends,

a, and connected at theirI front ends toa'partitioued pipe,'B, arranged in front of. the' Yfurnace and constructed as follows:

aga aan@ 4.

; Suspended from the partition-pipe in the ash-pitl chamber, I have arranged the cold-water supply-pipe C, rcommunie-ating with thecold-water sectional-pipe 'bi of said pipeBvby means ot'sho'rttubes e, as shown in fig. 3.

Each of said tubes c I have. provided withy proper globe-valves, c','wl1`ereby the operator is enabled to Y cutoff the supply of Water to the grate-bars; also, said valves serveas blow-olf valves to discharge v impurities and foreign matter in Asaid grates and throughpipe C.

To feed the water to they grate-bars A, the pipe C is connected, by means of a proper joint side-pipe, G', to acoldfwater feed-pipe, D, coming from the ordinary tank, pump, orother cold-water supply' source. Iu-said pipe D isa'suitable stop-cock, arranged to shut off -thc supply of water from the tank.

`To form an improved circulator forthe gratefbars- A,I connect with the side-pipe O', and incommuni.-

cation with the cold-water feed-pipe' D, the 'circulating-pipe E; by means of properjoint-pipesfc,"said pipeE is made to connect with the respective vmud-A vdrums F and F', as clearly shown in Iig. 1;

'Bysnch an arrangement oi`. parts a; continued circulation of the water from the boilers "and through the gratefbars A is achieved, and thusv said `:pipe E alsov serves as a feed-'pipe-to; ai1l-vgrates, conjointly with the cold-water feed-pipey Close to the joint of the respective -pipesv I) ,and E Iprovidethe latter with a balance check-valve,;G.

Said valve hasits stem and hub connected to `a proper lever, If/,f bearing ,the centerpoisefweights g, and said valve is so constructed that in its operation it shall be self-acting, remainingclosed'byv the equalization of'v prcssnresfrom the respective pipes D vandE, but openin g its-valve to permit uninterrupted circulation v fot' the waterfrom. the boilei-to`tl1e"gratefbars "lhusv the cold-water supplyfi'om theyfeed-pipe' D directly regulated to "enter the grate-.bars A, 'a'ndple` vented from entering the circulatorE. 1

-In the use of' one boiler I connect, in coinniiu'iica-- tion with` the steam sectional pipe?)2 ofthe partitionpipe B, at each end thereogthe steam-pipe H.l` -Th'e steam, o r steam and 1hot\vater, generated inthe .,gratesA, passing through 'said steam-pipe H,enter into the boiler or other receiver t l1ereoi',.as shown in The joint of said pipe yH with the boileiwill be; t inany proper mannerv so as to form the needed v .lo'form areceiving'and discharging-pipeIconstruct the pipe B, having arranged within the same a vertical diaphragm, l. Said pipe B, thus divided, forms a vcold-water sectional-pipe, b1, and the' steam, or steam" and hotwater, sectional-pipe bias clearlyshown iii steam-tight joint." In said stean1-pipe His a proper valve to. cutoff the supply of steam and regulate the passage thereof to the boiler.'v y l f `In case of twno' more boilers, and in the use ofai1- ditional grate-bars, the 'sameare f unitedin' communi-A cation-with the cold-water. supply-pipe Oand the steam-pipe I by means of'pr'oper bifurcated joints "i,

l being `arranged in s aidJ p'pe Ito regulate through the -same the supply of "steam tothe boilerand prevent :in'ig.3. f u

To facilitate the generation of the largest quantityvided with partitioned pipe j,

vit is plain'said pipes utilize the heat of the fire-bed,

of steam, I furthermore arrange grate-bars J, and support additional sections thereof upon the inclined bridge-wall of the furnace-chamber. Said grate-bars J are similar in construction to those of A, and prointo which the cold water and generated steam are Aseparated indepeiidently, the former to enter the grate-bars and the latter to enter the steam-pipe K to be discharged into the boiler.v i

To feed the bridge-wail grates with a supply of water, the cold-water sectional-pipe ofthe partitioned pipe 7' connects with the feed or circulating-pipe K', arranged in communication with the rear mudldrum 11".

To prevent reiow-of water tovsaid mud-drum and boiler, I provide said pipe K' with a balance checkvalve, k, self-acting, and constructed similarly to the valve G, as previously described. .I

The inclined grates J will connect by proper bifurcated joints to the circulating-pipe K' and the steampipe K, respectively, in case of two or more boilers, as previously described in case of the grate-bars A, and as shown in igsl and 2.

The pipes D and' E maybe arranged within or without the fire-bed. When arranged within the re-bed servingas additional grate-'bars or heaters.

By providing the pipe E with a spring-bend, E', as shown in fig. 1, the bad results ot' unequai'contraction and expansion caused by varying temperatures are sufficiently guarded against.

It will be observed that as each 'duplicate section of grate-bars disch. rges its generated steam, or ,stea'm and hot Water, independently of the remainin g sections, said grate-bars'are not` liable to become disabled by fuel and ,by oxidation, as the ungenerated*waterserves as a protector to, said bars; at the same time the attachment of said grate-bars is such that the same are readily removable in case of necessity.

rlhe construction and arrangement of all said parts are such that steam maybe generated in the most rapid manner and with the most practical advantages of safety, utility, and economy.

v Having thus fully described my said improvements,

What I claim, and desire' t'p secure by Letters Patent, is

1. rlhe gratebars A', formed iu duplicate sections Aland A2, having return-bend a, when arranged in combination with the cold-water sectional-pipe b1 and steam-sectional-pipe b2 of the partitioned pipe B,'and steam-pipes H and I, substantially as set forth.

2. 'llie grates A, partitioned pipe B, tubes @valves ci, asli-pit pipe C, joint-pipe G, in combination with the feed-pipe DAand vcirculating-pipe E, substantially 'as set forth.

3. The c-irculato'r E, spring-bend E', balance checkvaivve G, and feed-pipe D, when arranged within or without thefire-bed, invcombinatou with lthe pipes VC C', partitioned pipe B, and grate-bars A, substantially as and for vthe purpose set forth, A. l

4. rJhe grates J, acting as a bridge-wall, partitioned, pipej, bend or steam-,pipe K,in combination with the circulating or feed-pipe K', balance check-valve 1;,a-nd mnd-drum F', substantially as set forth. A

I have In testimony of said invention my hand in presence oi` v Y .l JOSEPH Witnesses: i
